Hundreds of impact craters on Mars contain diverse phyllosilicates, interpreted as excavation products of preexisting subsurface deposits following impact and crater formation. This has been used to argue that the conditions conducive to phyllosilicate synthesis, which require the presence of abundant and long-lasting liquid water, were only met early in the history of the planet, during the No...
The development of the Cyprus Stock Exchange together with the increasing trend of investors’ presence in financing activities has led to the importance of this market. In such circumstances, the first step towards a sustainable development of the Exchange is to support the investors. Risk of bankruptcy for the investee is a major challenge that an inexperienced stock investor encounters. In th...
پیشینه تحقیق: تغییرات ایمنولوژیک در بیماران مبتلا به اسکیزوفرنی، در دهه گذشته به شدت مورد توجه قرار گرفته است . بیماران اسکیزوفرنی دارای مقادیر مختلفی از سیتوکین ها و گیرنده های مربوط به آنها بخصوص اینترلوکین - 1 بتا و فاکتور نکروز توموری- آلفا در خون محیطی و مایع مغزی - نخاعی خود هستند و همچنین مطالعات متعددی نشان داده اند که میزان سرمی il-6 ، tnf-? و il-18در بیماران مبتلا به اسکیزوفرنی افزایش...
This paper uses a theory of composition based on existential and universal properties. Universal properties are useful to describe components interactions through shared variables. However, some universal properties do not appear directly in components specifications and they must be constructed to prove the composed system. Coming up with such universal properties often requires creativity. Th...
Using a strongly covariant formalism given by Carter for the deformations dynamics of p-branes in a curved background and a covariant and gauge invariant geometric structure constructed on the corresponding Witten’s phase space, we identify the canonical variables for Dirac-Nambu-Goto [DNG] and Gauss-Bonnet [GB] system in string theory. Future extensions of the present results are outlined.

Fifty-nine adults slept five nights with an Actigraph and answered two questionnaires related to sleeping quality and morningness/eveningness preferences. Next they performed a computerized attention task (the mathematics continuous performance test (MATH-CPT)) to assess various measures of attention. Results showed significant correlations between six attention variables and two measures of sl...
